Description
The present invention relates to a kind ofly can make the fragmentary or broken diffusing method of the solid particle agglomerate that floats on a liquid and implement the used equipment of this method.
Method and apparatus of the present invention is suitable for the agglomerate of fragmentary fine particle most, promptly have in the process of nuclear fuel of radiativity in recovery, the nuclear fuel of pulverizing is decomposed in hot salpeter solution, clarify salpeter solution then and obtain have a solid material that limits granularity.These tiny materials, its chemical constitution are to be base-material with other used metal of zirconium, molybdenum, ruthenium and manufacturing nuclear fuel, behind the clarification salpeter solution, for example, in a centrifugal rotation stillpot, become the indefinite solution of mud or concentration, accumulate in together in varying degrees.With the tiny material of these intense radiations after storage tank is placed a period of time, constantly stirred, for example used palsating equipment, then by suitable pipeline transportation to carrying out the place that vitrifacation is handled, there, in order to prevent that nuclear radiation from encasing it with glass lode ore material.
In the process that mud is transported to storage tank and these mud in storage tank between the storage life, the formed caking that varies in size brings serious problem.
Thereby the agglomerate of being made up of abrasive particle weares and teares the sweep of conveyance conduit.And these agglomerates will be in the non-turbulent flow districts of conveyance conduit or the pipe line area precipitation of rough inner-surface are arranged, and stop up piece and the sweep of pipeline is blocked thereby form.This obstruction piece or deposition piece have caused the problem that is difficult to solve, because they have strong nuclear radiation, therefore make any emergence treatment scheme all be difficult to implement.Because be difficult to simulate its operating mode, the flow characteristics of change equipment and mud also can not address this problem.
Another shortcoming that agglomerate had that varies in size that is transported in the mud in the storage tank is that these agglomerates are deposited on storage tank bottom, overslaugh storage tank and palsating equipment operate as normal.Owing in storage tank, carry out emergency processing and be difficulty especially, so wished very much before mud is transported to storage tank and can open the agglomerate in the mud that will be transferred is fragmentary.

Among Fig. 1, label 10 expression one horizontal concrete thickness plate, it can allow the groove 14 below upper area 12 that the people passes through and separate with one, and filling pending containing in the groove 14 will be by the liquid of fragmentary solid particle agglomerate.
To cover 24 upper ends that are fastened on garden tube 18 with bolt 25, garden tube 18 will be sealed.Sleeve pipe 26 is outstanding downwards from covering 24 lower surface, garden tube 18 in the downward extension in garden tube 18 coaxial cable ground.The thrower of using label 30 to represent is being carried in lower end at sleeve pipe 26 with bolt 28.Thrower 30 is made up of three parts 31,32 and 33, and they and garden tube 18 be axial line altogether.This three part is a lower member 31, the exterior part 33 on inside center parts 32 and top.
With bolt 34 bottom disc-shaped part 31 is fastened on the lower end of inside center 32.Parts 31 therein the heart have one with cylinder 18 nozzle 36 of the contraction of vertical axis altogether.The inlet chamber 38 that forms in the lower part of garden tube 18 is led in the major diameter lower end of nozzle 36.An admission passage 40 that forms in the thick wall part 18a of garden tube 18 also leads to inlet chamber 38, so that containing and will being incorporated into inlet chamber 38 by the liquid of fragmentary solid particle agglomerate.With a pump that does not show in the accompanying drawings pressure fluid is injected this equipment 16, injection pressure for example is at least 300KPa.
The bottom of the inside center parts 32 of thrower 30 has a bell part 43 and a top that forms Venturi tube 44, fixed installation lower member 31 below bell part 43.Between the bell part 43 of bottom and lower member 31, form a circular chamber 42.With nozzle 36 and garden tube 18 Venturi tube 44 bottoms of the axial lines circular chamber 42 that leads to nozzle 36 tops altogether.Form the lower inlet section 46 and a top outlet section 48 of short convergent than long flaring in the inside of Venturi tube 44.
A sealing O-ring 60 is housed on the outside surface of the bell part 43 in bottom, and its inside surface with the thickest part 18a of garden tube 18 above the opening of admission passage 40 has constituted sealing, and therefore, inlet chamber 38 completely cuts off with the remainder of garden tube 18.
The bottom of the exterior part 33 on the top of thrower 30 has garden annulus 49, with bolt 28 garden annulus 49 is fastened on the lower end of sleeve pipe 26, and garden annulus 49 is around around the Venturi tube 44.The garden annulus 49 of this bottom is installed on the thickest part 18a of garden tube 18 by two sealing O-rings 62.
The exterior part 33 on top also has a tubular portion 50 that forms in its upper end above the garden of bottom annulus 49, above Venturi tube 44, a cap shape part 51 is arranged.Tubular portion 50 around Venturi tube 44 around and with Venturi tube 44 coaxial inner conductors, and by the welding connecting link 53 carrying Venturi tube 44.In the circular passage 54 that forms between Venturi tube 44 and the part 33 passing away 58 that forms in the upper end of Venturi tube and the thickest part 18a at garden tube 18 is communicated with, passage 58 encircles between 60 and 62 at O-, leads to said groove.
The hole 64 that forms in the horizontal component on the top of the bell part 43 of bottom is communicated with the bottom of circular passage 54 with circular chamber 42.These holes are recycled a part of liquid and enter Venturi tube 44, will be described in greater detail below.
Contain to be preferably under the pressure of 300KPa by the liquid of fragmentary solid particle agglomerate and be admitted to this equipment through admission passage 40.The band press liquid that is introduced into inlet chamber 38 by the converging transition 46 and the divergent segment 48 of nozzle 36 and Venturi tube, flows through thrower 30 from bottom to top successively.Liquid stream in the nozzle 36 has produced high flow rate by Venturi tube 44.Therefore, if the flow of liquid that is introduced into equipment 16 near 5 meters
3/ hour, the external diameter of nozzle 36 is near 10 millimeters, and then the flow velocity of liquid can be near 18 meter per seconds.
Enter flow through the from bottom to top then liquid of initial flow of Venturi tube 44 of nozzle 36, and by being superimposed by the carried under one's arms flow of the injection that comes of hole 64 by the liquid of the said initial flow that enters circular chamber 42.Experiment shows that the flow of injection is very near initial flow.Subsequently, the liquid that is superimposed is with near 10 meters
3/ hour flow pass Venturi tube 44, said as following example.
For example bump against on the bell part 51 with the liquid that flows out at a high speed from its diameter, turn back again by circular passage 54 near the upper end of 40 millimeters Venturi tube 44.Then, a part of liquid flows out through passing away 58 slave units 16, and remaining liquid enters circular chamber 42 circulations by hole 64.
Enter flow through the then liquid of Venturi tube 44 of nozzle 36 and have very big radial velocity gradient, promptly be far longer than along the flow velocity of the wall flowing liquid of nozzle and Venturi tube along the flow velocity of vertical axis at this near axis flowing liquid.Flowing liquid and solid particle agglomerate are subjected to very big shearing force continuously in nozzle 36 and Venturi tube 44, make these agglomerates by fragmentary.
Be subjected to the particle of above-mentioned shearing force effect to be subdivided into smaller particles,, no longer can be enough to till fragmentary these particles for quite little the shearing force that causes by the radial velocity gradient of the liquid that enters nozzle 36 and Venturi tube 44 until its size of these smaller particles.
For example, the mean diameter of the particle that suspending liquid contained of passage of having found to enter equipment 16 of the present invention is near 30 microns, by behind the passage, the mean diameter of particle is reduced between 10 to 15 microns first, and the mean diameter of process circulation back particle is reduced near 5 microns.
In another experiment, make by the diameter of particles suspended greater than 100 microns.The liquid of initial access arrangement 16 contains 4% this particle, flow through passage first after, from the liquid that Venturi tube 44 flows out, only contain 3% particle, through after the circulation once, said percentage is reduced to 1.5%, after twice circulation, is reduced to 0.7%.
Owing to exist abrasive particle in processed liquid, and this liquid also has corrosivity, and therefore, the part that is acted on of equipment 16 promptly mainly is nozzle 36 and Venturi tube 44, obviously can damage quickly.Thereby, to equipment shown in Figure 1, can thrower be split out by the top zone 12 that allows the people pass through, so as need the time it is more changed.
In order to change, operating personnel can pull down bolt 25 in zone 12, unload lower cover 24, and lid 24 is being with thrower 30 to be removed together by sleeve pipe 26.As the case may be, said thrower can be replaced whole or in part.Thereby thrower 30 is installed on the sleeve pipe 26, so that dismantle it by bolt 28.When on parts 31, forming nozzle 36, can parts 31 be detachably fixed on the parts 32 with Venturi tube 44 by bolt 34.
With reference in the described equipment of Fig. 1, processed liquid flows to the top from the bottom in by nozzle 36 and Venturi tube 44 formed throwers in front.In fact, experiment shows, makes liquid flow to the top from the bottom in said thrower, can obtain high-level efficiency.In second embodiment of equipment of the present invention, downward liquid flow is passed through thrower.Below, be described in greater detail with reference to Fig. 2.
